CONVEYER.

Application filed October 5, 1925. Serial No. 60,596.

provide a'structure that will lower such goods from one elevation to another, and do so without crowding or congestion at any point, and without damage to the goods. I r-.ccomplisl'i this object,v and other desirable results that will hereinafter appear, by means. of the construction illustrated in the accompanying drawings, which are a part oi this application ior Letters Patent.

like characters of reference indicating likeV parts throughout the several views thereof, and in which 1 is a side elevation ot my device.

-F ig. 2 is a plan view thereof. L

Fig. $5 is a transverse section ot the same.

Fig. is a 'fragmentary perspective view of the. upper member o'l: my device .in preierred form.

Fig. 5 is a view similar to Fig. Ll', but showing a niodiiied form of construction.

-Fig. is a transverse section of the form shown in Fig. 5.

is a transverse section of the modified form shown in AFig. 6.

In general my device consists' 'of a traveling belt conveyer obliquely positioned to lower goods thereupon,` and a member mounted upon said conveyer :trame and having yieldable port-ions adapted to Contact with the goods in passage and retard their movement to the velocity ot the traveling conve},'er, and thus to lelii'ninate all crowds.

ingl and congestion which occurs when lgoods are lowered on gravity conveyers.

For convenience oi construction I mount my traveling conveyer 8 upon rollers 9 mounted upon side members lO ot asupporting trame'. Return rollers 11 and 12 are provided at cach end of the trame, and the roller 11 is driven by mechanism mounted within a yoke 13 .upon theV frame. The driving mechanism may be any of the well known and used devices, such as an electric motor and transmission gears or chains, and therefore is not shown in the drawing, forming no part of the invention. Supporting rollers 14 are provided forY the re.-

turn portion of the traveling conveyer. `The whole is mounted conveniently upon supports 153 and 1G, the former being upon the lower floor where the goods are to be deber 18.

posited, Vand the latter upon the upper floor whence the goods are to be removed, as shown in F ig. 1.` A receivingconveyer 17 is positioned to lreceive the goods'from my device, and said conveyer is also driven from the mechanism mounted upon the yoke 13 andis not shown inthe drawings.

Mounted parallelwith the traveling conveyer, and most conveniently` above the same, is a' member 18, and upon this member are disposed devices of yiel-dable character adapted to Contact with the boxes upon the'traveling eonveyer as they pass along. A preferred form of these devices is a series of connected articulated bars 19, moz-fteonveniently constructed of angle bars as shown. At their pivotal connecting points t-hese bars are mounted upon stems 20, -which stems are'slidably mounted in said member 18 and in clips Q1 secured thereupon. Springs 29. are'mountedl upon said stems between the clips 21 and pins 23 in said stems 20, said springs serving to retain the stems and their attached bars 19 in lowermost position, or position in which said bars are urthestremoved from'mem- One endofeach ot' saidl bars 19 is slotted as at 24e-*in Figft, and these slotted ends are mounted adjacent each other Aupon one of the stems 20, Ythus allowing the bars to rise and fall as the stems are pressed upward. The member 18 is preferably mounted 'above the traveling conveyer, and is supported in place by yokes 25 mounted upon the side members 10 of the trame.

- rlhe distancebetween the bars 19 and the traveling conveyer 8 is made a trifle less than the depth of the boxes 26 to betransm ported and lowered with thel device, the result being thatA as the boxes pass along down the device'the bars Contact in turn with the boxes, and said bars are moved thereby away from the conveyer compressing the springs 22. Thus the traveling boxes are retarded by the pressure ot the bars 19 thereupon and crowding and congestion I crowding and congesting effect of gravity no matter how steep the incline of the devicel may be.

In the modified form of my device illustrated in Fig. 5, I provide spring members secured upon the member 18 and bent away therefrom for a portion of their length, and then bent substantially parallel with said member 18, as shown in Fig. 5. In this construction the lower ends of the stems 3l simply contact with the spring members 30.

At the lower or discharge end of my device, where the boxes are deposited upon the conveyer 17 I provide an apron 32 mounted upon the lower end of t-he frame, and adapted to receive the rearward ends of the boxes as they leave the conveyer 8. The rearward ends ot the boxes thus slide down the apron and do not subject the contents to any jar as the boxes are deposited upon the conveyer 17.

My invention may be made of any size. and constructed .of any materials deemed convenient and suitable for a device oli this character7 and while I have illustrated and described a form oli' construction and arrangement ot parts found desirable in materializing my invention, I wish .to .include in this application all mechanical equivalents and substitutesv that may fairly be considered to come within the scope and purview of my invention as defined in the appended claims.

Having disclosed my invention so that others may be .enabled to construct and to use the same. what I claim as new, and desire to secure by Letters Patent is 1. An endless traveling eonveyer; a mem ber parallel to said conveyer; and yieldably lel thereto; articulated bars upon said parallel member adapted to Contact with material .upon said conveyer; and spring actuated mechanism to yieldably hold said bars in operating position.

1. A traveling belt'conveyer; :a member parallel to said conveyer and adjacent thereto; a series of pivotally connected articulated hais; stems for mounting said bars at each of saidpivotal connections; and springs upon said stems holding said bars at their extreme position from said member.

5. A traveling helt conveyer; a member parallel to said conveyer and adjacent .thereto; a plurality oit bars subst-.antiallyV parallel to said member and suspended therefrom to contact with material upon said conveyer: and spring actuated stems mounted upon said member and coacting with said bars to keep the latter at their extreme distance from said member.

In witness whereof I claim the ieregoing as my own, I hereunto alien( my signature at Portland, county et vldultuomah. State et Oregon, this 9th dav of Sept., 1925.
